When the nerve canal is restricted and other measures such as physiotherapy did not provide relief, the doctor will consider a surgical treatment of spinal canal stenosis. The so called microsurgical decompression relieves the spinal canal and targets the constricted spot.
A relatively narrow spinal cord canal may already exist since birth or develop later due to spondylolisthesis. Alternatively, in some forms of deterioration of the spine, the spinal cord canal can get narrower over time due to additional tissue collecting. This constricting material and bony components of the facet joint can be removed by surgery. In order to maintain the stability and biomechanics of the spine, only the actually disturbing structures will be removed.
For this microsurgical procedure, the incision only has to be as long as the length of the constricted nerve canal. Through this incision, the microsurgical instruments are then inserted under microscopic observation. Usually, patients’ range of movement already improves a few hours after the procedure. After about six to eight days, patients are allowed to leave the hospital and can begin with the recommended rehabilitation.
